UNITED STATES ATENT Oriana FREDERICK It. HAWLEY, OF SYRACUSE, NEW YORK.

CHURN.

SPECIFICATION forming part of Letters Patent No. 223,286, dated January 6, 1880.

Application filed November 21, 1879.

To all whom it may concern Be it known that I, FREDERICK R. HAW- LEY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Uhurns, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The nature of this invention consists, essentially, in a novel construction and combination of an upright frame, supporting on its upper end the vat or receptacle for the cream to be churned, and rocking with its base on three or more separate and distinct bearingpoints in an are described from one or more centers, and constrained in its normal position by a spring or springs connected with its center and exerting their power in the direction of the radius of the are, by which improvement a thorough and perfect dashing action of the cream is produced, and the process of churn ing is greatly facilitated and accelerated.

It also consists in certain peculiarities in the detail construction of the aforesaid apparatus, all as hereinafter more specifically set forth and described.

In the accompanying drawings, Figure l is a side elevation of my invention; Fig. 2, an end View of same, with a portion of the lower end cross-bars broken away to more fully illustrate the arrangement of the springs. Fig. 3 is an inverted view of the churn-vat and its connection with the oscillating or rocking frame, and

Fig. 4 is an isou etric view of the bed-piece or stationary frame upon which the apparatus is operated.

Similar letters of reference indicate corresponding parts.

A A are two rockers, having their under sides or bearings formed with a short flat portion, a, at the center, and straight or very slightly curved surfaces I) I) deflecting from the ends thereof, forming angles 00 at their junction with same. From the ends of the flatparts I) b the rockers are again deflected to their extremities to form angles (1 d at the end of the parts I). The object of this peculiar construction of the rocker is to maintain the fulcrum near the center until the rocker is carried nearly to the desired extent, and then suddenly transfer the fulcrum to that point, thereby gaining great leverage on the oscillating frame and producing at the extremities of its stroke jars, which, in conjunction with the springs hereinafter described, tend to repel the thrust of the oscillating frame and cause the cream to dash with great force against the ends of the churn-vat, which is carried on top of the oscillating frame, in the manner hereinafter more fully described.

The rockers are connected with each other by cr'ossbars c at the ends and a plate, f, at the center, which latter is secured to the top of the rockers. To the plate f are attached two uprights, g g, and from the ends of the rockers are extended braces h h, inclined toward the center, or arranged radially to the arc of the rocker. To the upper end of the said uprights and braces is attached a horizontal frame, 6, upon which is mounted the churn-vatB, having on its bottom cross-cleats 7a, fitted against the side of a cross-bar, l, of the frame 1', and abutting with its ends against the side rails of said frame, thereby preventing lateral displacement of said vat, which is further securedin its position by pins m inserted through the crossbars 7c and l.

To the uprights g 9, near the upper end thereof, is attached a cross-bar, n, to which are attached pendent springs o 0, having connected to their lower extremity a block, p, which is drawn downward by a screw-bolt, r, secured at one end to the stationary base or bed upon which the oscillating frame is operated. The upper end of the bolt 1' passes through the block 12, and is provided on top thereof with a thumb-nut, by which 'the tension of said springs is adjusted.

C is a horizontal frame, formed of two side rails, 8, having a vertical flange, t, on their inner top edge, which rails are connected with each other by cross-bars a at the center and ends of said frame. By bolts passing through the end cross-bars and into the floor theframe U is firmly secured in its position.

The rockers A A are mounted on the rails s, the flange t of which serves to guide the rockers in their movement. The central portion of the rocker A is provided on its under side with a metal plate, y, which bears on a plate, v, attached to the rail 8, and thus guards against wear and abrasion of the main structure. By

means of lugs to on the ends of the plate g entering aperturesin the plate 1;, and also by' dowel-pins or on the rocker at the angles (Z d, engaging holes in the rails s, the rocker is pre vented from sliding.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is

l. The rockers A A, formed with angles 0 c and d (I, in combination with the vat-supporting frame, the springs 0, and bed 0, substantially as described and shown.

2. The combination of the rockers A A, formed with angles 0 c and d d, and provided at their center with the plate y, having lugs w, and at the angles 61 d with dowel-pins x and the rails 3, provided with plate 0, having apertures for the reception of the lugs of plate y, and with apertures at the point of contact with the angles 61 of the rockers, substantially in the manner and for the purpose specified.

3. The combination of the stationary frame 0, the oscillating frame having its rockers formed with angles 0 0 and d d, and the crossbar 11,, attached to the uprights g, the springs 0, connected at one end to the said cross-bar and at the opposite end to the block 1), the adjustable rod 1", connectin the said block with the stationary frame, and the vat B, mounted on top of the oscillating frame, all constructed and combined substantially in the manner and for the purpose set forth.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga and State of New York, this 15th day of November, 1879.

FREDERICK It. HAwLnY.
